25-Crater Hopmann.jpgA postcard from the Far-Side: Hopmann Crater72 visiteThis image, taken by the advanced Moon Imaging Experiment (AMIE) on board ESA’s SMART-1 spacecraft, shows one quarter of crater Hopmann - an impact structure about 88 Km in diameter.
AMIE obtained this image on January, 25th, 2006 from a distance of about 840 Km from the surface, with a ground resolution of 76 mt per pixel.
The imaged area, not visible from Earth because it is located on the Far-Side of the Moon, is positioned at Latitude of 51,7º South and Longitude 159,2º East. It covers a square of about 39 Km per side.
Nota: osservate con attenzione il bordo del cratere Hopmann e poi cercate di spiegare e di spiegarVi come un margine "infossato" come quello che vediamo in questa discreta (anche se leggermente sfuocata) immagine possa essere il semplice risultato di una, tutto sommato semplice, "meccanica di impatto".
Confrontate questo cratere, p.e., con Tsiolkowsky, Arago-C, Copernicus e Clavius e poi, se volete, provate a redigere una serie di elenchi di crateri lunari associati sulla base della loro apparenza esteriore (e cioè in base alla loro somiglianza): noterete che, delle due l'una:1) o le tipologie di impatti sono migliaia di migliaia di milioni (il che è vero solo in teoria) o 2) è ragionevole supporre che alcuni crateri potrebbero non essere il mero prodotto di un impatto.
E nel ragionarci sopra, tenete a mente il Rasoio di Okkam...

Moon-SouthernSide.jpgThe Southern Highlands of the Moon (Moretus and Curtius)72 visiteCaption NASA:"The Moon's South Pole is near the top of this sharp telescopic view looking across the Southern Lunar Highlands. Recorded on August 3rd, 2007, from Tecumseh, Oklahoma, planet Earth, the foreshortened perspective heightens the impression of a dense field of craters and makes the craters themselves appear more oval shaped. The prominent crater in the foreground, Moretus, has a diameter of 114 Km and lies just west (left) of the Moon's Central Meridian. For large lunar craters, Moretus is young and features terraced inner walls and a 2,1 Km high, bright central peak, similar in appearance to the more northerly crater Tycho. Just to the right of Moretus is the 95 Km diameter crater Curtius.
Curtius has older, rounded walls marked by smaller, more recent impact craters".MareKromium

13-Flamsteed Crater.jpgFlamsteed Crater and Oceanus Procellarum71 visiteCaption NASA originale:"Lunar Orbiter 4 image showing the 20 Km Flamsteed Crater on the Moon. Flamsteed is the large crater near the bottom of the image. A broken ring of bright ridges, probably the rim of an older crater nearly covered by the later Oceanus Procellarum mare basalts, can be seen. The ring is about 100 Km in diameter, and a concentric wrinkle ridge is evident within the ring. The Surveyor 1 spacecraft landed in the upper right portion of the ring. North is up (Lunar Orbiter 4, frame 143-H2)".
